Understanding the Indian Monsoon
The climate of India is strongly influenced by the monsoon winds. The term ‘monsoon’ refers to the seasonal reversal in the wind direction during a year. This quiz focused on the mechanism of these winds and the seasons they create.
Key Mechanisms of the Monsoon
The formation of the monsoon is driven by several factors:
- Differential Heating: Land heats up and cools down faster than water. In summer, low pressure develops over the Indian landmass while high pressure exists over the sea, drawing winds inland.
- ITCZ Shift: The Inter-Tropical Convergence Zone (ITCZ) shifts north over the Ganga plain in summer, creating a ‘monsoon trough’ of low pressure.
- Jet Streams: The presence of the westerly jet stream north of the Himalayas and the tropical easterly jet stream over the Indian peninsula during summer influences the arrival of rains.
The Four Seasons
India generally experiences four distinct seasons:
| Season | Months | Key Characteristic |
|---|---|---|
| Cold Weather | Mid-Nov to Feb | Warm days, cold nights, frost in north. |
| Hot Weather | March to May | Rising temperatures, local storms like ‘Loo’. |
| Advancing Monsoon | June to Sept | Widespread rainfall, South-West winds. |
| Retreating Monsoon | Oct to Nov | Transition period, cyclones in Bay of Bengal. |
Burst and Break
The sudden onset of rainfall in the first week of June is called the ‘burst’ of the monsoon. Intervals of dry spells during the rainy season are known as ‘breaks’ in the monsoon.
